Custom Caravan Off-Grid Power Systems in Melbourne

Tired of paying premium campsite fees just to plug into mains power? Or maybe you’re dreaming of pulling up by a quiet river in regional Victoria, brewing a proper espresso, and running your air conditioning without hearing a noisy petrol generator hum all night.

At Nav Electrical Group, we engineer robust, reliable, and completely custom caravan off-grid electrical systems designed for the Australian outdoors. From our Melbourne hub, our qualified mobile auto electricians design and install seamless 12V and 24V power setups that let you live comfortably off the grid for days—or weeks—on end.

Whether you’re doing a full canopy build, upgrading an older caravan from lead-acid to lithium, or starting fresh with an off-road camper trailer, we bring the workshop directly to your driveway.

What Powers a Reliable Off-Grid Caravan Setup?

An off-grid rig isn’t just about throwing a solar panel on the roof; it is about balancing how you store, charge, and consume power so you never wake up to dead batteries and spoiled food.

We assess your specific daily appliance draw and build balanced systems using industry-leading gear like REDARC, Victron Energy, and Enerdrive:

1. High-Capacity Lithium (LiFePO4) Battery Banks

Old-school AGM and lead-acid batteries are heavy, slow to charge, and degrade if dropped below 50% capacity. We install lightweight Lithium Iron Phosphate (LiFePO4) batteries that allow up to 90% usable depth of discharge, charge up to four times faster, and shave massive weight off your caravan’s payload.

2. Matched Solar Arrays & Smart Regulators

Maximise every ray of Victorian sunshine. We install high-efficiency, hail-resistant rooftop solar panels paired with intelligent MPPT (Maximum Power Point Tracking) solar charge controllers. MPPT technology pulls up to 30% more power from your roof compared to standard regulators, keeping your bank topped up even on overcast days.

3. Pure Sine Wave Inverters

Want to run domestic 240V appliances like an induction cooktop, kettle, hair dryer, laptop charger, or caravan reverse-cycle A/C? We wire dedicated Pure Sine Wave Inverters safely into your system with automatic transfer switches, ensuring clean power that won’t damage sensitive electronics.

4. DC-to-DC In-Vehicle Charging

Don’t waste driving hours. A properly wired DC-DC battery charger with an Anderson plug connection draws power directly from your tow vehicle’s alternator while you drive, pumping reliable charge into your van’s house bank before you reach camp.

5. Bluetooth Power Monitoring & Shunts

Take the guesswork out of your remaining power. With digital displays and smartphone Bluetooth integrations, you can check your exact state of charge (SoC), power draw, and solar input at a quick glance from your camp chair.
